Recent National Weather Service and international model runs indicate Shanghai's August 5 maximum will likely reach 33–35 °C under the influence of a persistent subtropical ridge and southerly flow. Afternoon convection and increasing cloud cover introduce key uncertainty, as earlier or heavier showers could cap temperatures near 33 °C while clearer breaks allow brief spikes toward 35 °C. These conditions align with typical early-August climatology for the Yangtze River Delta, where humidity and weak steering winds limit rapid changes. Updated model guidance and local observations over the next 48 hours will refine the precise peak, directly influencing the narrow spread between the leading market outcomes.
